Firstly the indexes weights are determined with F-AHP(Fuzzy Analytic Hierarchy Process) evaluation methods,then the attribute value of evaluation index system are calculated with the multi-attribute dependent function according to the corresponding attributes.

In this paper,a time-cost-quality trade-off optimization model is set up by using multi-objective optimization theory and multi-attribute utility function theory.

To solve comprehensive multiobjective optimization of implementation scheme about time,cost and security in project logistics,a time-cost-security tradeoff optimization model,which was based on decision network planning technique and multi-attribute utility function theory,was proposed.

The partition function and correlation functions of the Ising model on a diamond fractal lattices;

The relative populations of states of 4￣He and 8￣Be were extracted from p-t and α-α correlation functions, respectively.

With the correlation functions we calculate the Lebowitz length.

The paper points out that incidence function of matter-element extension model is not convenient to calculate,and mutual exclusion of indexes has not been solved;so it has an influence on applied range of matter element analysis method.

Based on the extenics and incidence function, a kind of method for selecting object market is erected; a disinfector instance is cited, in order to illuminate the applying process.

Aiming at the problem of expansive scale of expansive soils,the paper constructs a new interval incidence function.
